IMPROVEMENT IN MACHINES FOR MAKING WROUGHT-NAILS.

Specification forming purt of Letters Patent N0. 98,008, dated December 2l, 1869.

To all whom it may concern:

Be it known that I, DANIEL ARMSTRONG, of Chicago, in the county of Cook and State of Illinois, have invented an Y Improvement in Nail-Machines3 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enablev those skilled in the art to make and use the same, reference being had to the accompanying drawings, and letters marked thereon, making a part of this description, in Which- Figure l is a perspective representation of my improvement; Fig. 2,. an elevation of a partappertaining thereto broken 0E from the main shaft; Fig. 3, (drawing 2,) a plan view of the device as it is arranged with some of the parts of Daniel Dodges nail-machine, patented August 23, 1859,- Fig. 4, an elevation of the same.

This invention relates to an improvement in that class of machines which are designed for manufacturing Wrought-nails, but more especially horseshoenails; and its nature consists in the construction and arrangement of the gearing and frame, and in the application of a housing to an internal gear-Wheel, Whereby the machine is greatly simplified, made to run more steadily, Wear longer, and not become choked with the chippings of nails, as the Whole is hereinafter fully specied. l

A represents a substantial frame Work, which is supported on legs J, in the usual manner, and Which is so formed as conveniently to support the Working parts of said Dodges machine, hereinafter referred to in detail.

D represents the main shaft of the machine, which gives motio'n to the eccentric 2 and dies 3 4 for making nails, in the usual manner.

In order to prevent backlashin g of the gearing, the cam-shaft C is driven direct by means of an internal gear-Wheel, G, which is put in motion by a pinion, F, attached to the end of shaft D.

The cam 5, which operates the rock-shaft 6, is fastened to the shaft O of Wheel G, by means of which, there being no backlashing, the clamp 7, Fig. 4, always holds va nail-rod in proper position for the dies to forge nails; and in order to prevent chippings of nails and scales of iron from falling down upon the cogs of Wheel G and breaking the gear, or interfering with the successful Workin g of the machinery, I place a housing, I, over the lower and inner periphery of the Wheel, and fasten it rigidly to the frame A, and thereby prevent any accident from the above causes, notwithstanding tlie machine is driven with great speed.

By means of this construction and 4arrangement the difficulty of backlashing ofthe cogs, and lost motion occasioned thereby, is entirely obviated, and brings the machine nearer to perfection than any improvement previously put upon it. l

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of Wheel G, frame A, shafts D C, pinion F, and housing I, constructed and arranged as and for the purpose set forth.

DANIEL ARMSTRONG.
